ATTORNEYS United States Patent PLASTIC NOZZLE MOUNTING AND METHOD OF FGRMING SAME Sylvester L. Flugge, Glen Ellyn, and John Henchert, River Forest, 11]., assignors to Continental Can Conn 'pany Inc., New York, N. Y., a corporation of New York Application April 27, 1955, Serial No. 504,242 11 Claims. (Cl. 222-566) The invention relates generally to metallic receptacles and primarily seeks to provide a novel plastic nozzle mounting on a top or breast portion of a container and which not only is sturdy and neat in appearance but also provides an eflicient liquid seal and is secure against turning of the nozzle relative to the top or breast portion when a screw cap is secured thereon.

An object of the invention is to provide a nozzle mounting of the character state-d wherein the nozzle includes a tubular body and a mounting base extending outwardly from the lower end of the body and having an annular anchoring and sealing rib upstanding from its periphery, and the container breast has a nozzle body receiving opening therein surrounded by a downwardly opening channel embracing the nozzle base rib and defined by a channel base merging inwardly into an inwardly and downwardly curled annular edge and outwardly into a downwardly extending upright annular wall, and an annular bead in the wall indenting the nozzle base and securing the nozzle base rib in liquid sealing assembly in the channel.

Another object of the invention is to provide a nozzle mounting of the character stated wherein the inner portion of the nozzle rib receiving channel is continued in an inward and upward curl to terminate in an annular edge lying against the nozzle body.

Another object of the invention is to provide a nozzle mounting of the character stated wherein the nozzle receiving opening defining edge is embedded in the nozzle. A further object of the invention is to provide an improved method of forming a nozzle mounting of the character stated including the steps of forcing the nozzle outwardly through the breast opening to place the base rib firmly in the receiving channel, and while so holding the nozzle, beading the upright wall into the nozzle base to secure the mounting.

A still further object of the invention is to provide an improved method of the character stated including the step of preforming a groove in the nozzle base in which to receive the nozzle securing wall bead.

With the above and other objects in view that will hereinafter appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claims and the several views illustrated in the accompanying drawings.

'Figure 5 is a view similar to Figure 4 illustrating the completed mounting as shown in Figure 1.

Figure 6 is a view similar to Figure 3 illustrating a modified form of the nozzle receiving breast opening.

'Figure 7 is a view similar to Figure 4 illustrating the step of securing the nozzle in the form of mounting opening shown in Figure 6.

Figure 8 is a view similar to Figure 5 illustrating the completed nozzle mounting of Figures 6 and 7.

In the example of embodiment of the invention herein disclosed, the improved nozzle mounting is incorporated in -a container structure including a body 5 having a top or breast 6 secured thereon by a conventional double seam 7. The nozzle to be mounted preferably is molded from a deformable, resilient plastic, such as polyethylene to include a tubular body '8, externally threaded at 9 and having an outwardly extending base 10 provided with an annular, upstanding anchoring and sealing rib 11. An annular groove 12, preferably but not necessarily, is preformed in the peripheral outer surface of the base 10 for a purpose to be described hereinafter.

The container breast 6 has a nozzle body receiving opening 13 formed therein, the same being surrounded by a downwardly opening annular channel defined by a channel base 14 merging inwardly into an inwardly and downwardly curled annular edge 15, and outwardly into a downwardly extending upright annular wall 16.

In the formation of the mounting, the nozzle body 8 is forced upwardly through the opening 13 to place the annular rib 11 firmly in the channel 14, 15, 16, as by employment of the pressure applying or sealing element 17 illustrated in Figure 4, and while backing up the channel edge 15 and the roll base rib 11, as by a back- 'ing tool 18, a beading tool or roll 19 is applied to the upright channel wall 16 to indent a bead 20 into the rib 11, or in the groove 12 preformed therein, in order to secure the nozzle base rib 11 liquid tight in the mounting channel. The indenting of the head 20 also serves to deform the rib 11 so that the raw metal edge 15 is covered by or embedded in the deformable plastic as at 21. In this manner the nozzle is very firmly secured in the mounting, providing a sturdy mounting of neat appearance, and one which is liquid-tight and devoid of presentation of raw metal edges, and also one in which the nozzle body is secure against rotation relative to the container breast 6 when screw closure caps are threaded thereon. v

'Inthe form of mounting shown in Figure 6 the nozzle receiving mounting opening in the container breast is formed as in the previously described illustrations except for the fact that the inner part of the channel is extended into an inward and upward curl at 22 terminating in an opening defining edge 23 which during the forcing in of the nozzle becomes embedded at 24 in the nozzle body. After the nozzle has been inserted and the annular rib thereof firmly pressed into the receiving channel, the outer wall of the rib receiving channel is beaded at 25, in the manner and for the purposes previously described.

It will be apparent by reference to Figure 5 that in the form of the invention illustrated in Figures 1 through 5 the plane in which the center of the bead 20 lies is displaced slightly endwise toward the base end of the nozzle from the plane in which the curl edge 15 lies, thereby to assure firm locking of the nozzle head in the receiving channel and the deformation of the nozzle rib 11 so as to embed and eifectively protect the raw metal edge 15.

In the form of the invention illustrated in Figures 6 through 8 it is to be noted that the plane in which the nozzle securing head 25 lies is above the lower extremity of the curl 22 so that the beading opposes the inner wall of the nozzle rib receiving channel and thus assures a very secure anchoring of the nozzle rib in the channel.

While specific method steps and structural details of the mountings have been described herein, it is to be under.-

stood that these steps and features may be varied in prac tical developments of the invention without departing from the spirit and scope thereof as defined in the appended claims.
